Subject: [PATCH lib/bitmap 9/9] rcutorture: Use "all" and "N" in "nohz_full" and "rcu_nocbs"
Date: Wed, 3 Mar 2021 15:56:16 -0800 [thread overview]
Message-ID: <20210303235616.22093-9-paulmck@kernel.org> (raw)
In-Reply-To: <20210303235526.GA21868@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
This commit uses the shiny new "all" and "N" cpumask options to decouple
the "nohz_full" and "rcu_nocbs" kernel boot parameters in the TREE04.boot
and TREE08.boot files from the CONFIG_NR_CPUS options in the TREE04 and
TREE08 files.
